CONTINUOUS TRACK-LIGHT AND AUTOMATIC SIGNAL;

act descri tion of the invention, such as will enable otiers skilled inthe art to which it appertains to make and. use the same, refer encebeing had to the accompanying drawings, and to the letters and figuresof reference marked thereon, which form a part of this specification.

This invention relates to new and .useful improvements in signalingdevices for cars, automobiles, &c.,' and the object in view is to roducea light so arranged that its rays will ollow the track about curves andcause a signal to be sounded as the car passes about a curve. a

The invention comprises various details of construction, combinationsand arrangements of arts which will be hereinafter fully describe andthen specifically defined in the appended claims.

illustrate my invention in the accompanying drawings, in which p IFigure 1 is a side elevation showing the aplication of my invention toan electric car.

i 2 is a bottom plan view.

Fig. 4 is a slight modification of the apparatus showing the same asapplied to an automobile.

Reference now being had to the details of the drawings bv letter, Adesignates the plat-- form of a car, a bolster and C a rod verticallydisposed and mounted in suitable bearings upon the car and provided witha sprocket wheel B at its lower end. E designates a chain which passesabout said sprocket wheel and its ends are fastened to the bolster, one

" upon either side of the centralpivotal portion thereof, whereby, asthe holster turns, a partial rotar movement will be imparted to said.rod 0. on the upper portion of said rod is fitted a. amp F having asocket F -fitting over the upper s uared end of the rod, and Gdesignates a inged member which is adapted to fit down over the upperend of the socket portion of the lamp to hold the same in place.Mounted. u on said rod is a fiber block H, preferably 0 cylindricalform, and

has a copper hand K. extending partially about its circumference. Aspace intervenes between the ends of said copper band, form-- ing aninsulation. Metallic arms N are fastened. to a block 0 upon the car andthe free ends of said arms are adapted to contactyieldingly against thecircumference of the copper band whereby, when the cylinder upon whichthe band is mounted turned so as to throw the free ends of said arms incon tact with the cop or band, the circuit will. be closed and scum asignal, suitable connections being made between said arms fori'ningcontact points either with the line wire or with a storage battery orother source of supply. A suitable switch lever J is mounted upon thecar andhas electrical connection with one pole of the battery, and J isthe contact point which is electrically connected with the source ofenergy and against which said lever is adapted to be thrown when it isdesired toput the contact points in circuit. Saidswitch. mechanism isprovided so that the signal may be conveniently thrown out of operativerelation if desired by the motorman or other person when, for anypurpose it may be desired not to have the signal sounded.

In the drawings, I have shownthe a pl i ,hftiie sprocket one end to theiever W on tne bottom of the lamp 3 From the foregoing, it .il be notedthat, by the provision of an. a teparatus showi': and described, anelectric or other light may be made to throw its rays upon the track. to

be followed by the car instead of having the light fixed as is cornice.the case at present andsvhich will throw the 1t directl in front 0' thecar and not upon curves aoout which a car is to pass. is the holsterturns,

in lieu thereoi a the circuitis corner, the bolster returning to itsnormal position. will cause the light to be tl'irown -dire.ctly inadvai'ice of the car and the sigi'ialing will cease the circuit isbroken by the contact points oi the arms leaving the copper band andcoming in contact with the insulation intermediate the ends thereof.

What I claim to be new is l. In combination with a car, an uprightrotatable rod, a lamp mounted thereon, a fibrous cylinder hired to said.rod, a. metallic band extending partially about said cylinder, contactpoints mounted upon. the car and adapted to bear againstthecircumference of said cylinder, electrical circuit connections withsaid points, a bolster, conl'iections between the same and said rodwl'iereby, as the bolster turns, a rotary movement will be imparted tosaid rod and the circuit closed, causing a signal to be soundedsimultaneously with the turning of the lamp, as set forth.

2. In combination with a car, anupright rotatable rod, a lamp vmountedthereon, a fibrous cylinder fixed to said rod, a metallicband extendingpartially about said eylinder,'

contact points mounted upon the car and adapted to bear against thecircumference of said cylinder, electrical circuit cormections with saidpoints, a bolster, a sprocket wheel Iii) retaining member mounted uponthe car and.

engaging said socket member, a cylinder of fibrous niateriai upon saidrod, ametallic band partially surrounding said cylinder, contact pointsmounted upon the car and adapted to bear against said. band andcylinder, and electric connections'with said points, as set forth.

In testimony whereof I hereunto ailix my signature in the presence oftwo witn esses.
